IS A RAINWATER HARVESTING SYSTEM RIGHT FOR YOU?
Do you want to reduce your carbon footprint?
Do you want to increase your use of water conservation techniques?
Have you been affected by extended periods of drought?
Has your water utility imposed water restrictions in the past?
Are you building a new house and considering well water for your water supply?
Texas Rainfall Catchment offers a variety of services tailored to your specific needs. For an estimate
on the purchase of a system of 5,000 gallons or more, call 210-587-7037. If you are thinking about putting in a system of 2,500 gallons or less, doing it yourself will be much more cost-effective than having a professional rainwater harvesting installer do it for you. Texas Rainfall Catchment offers design services and consultations for systems less than 5,000 gallons.
We will work with your builder or architect to design and install a rainwater harvesting system
Get us involved early so that the rainwater harvesting system does not conflict with the septic system or any out buildings
Metal roofs (galvalume) work best
Use PVC or PEX supply lines inside the house instead of copper
Gray water systems require separate supply lines
Plan gutter, downspout and tank locations for efficiency and to avoid spillage
Plan filtration and purification locations for easy access
Use native, drought-tolerant plants in landscaping
We can retrofit an existing home with potable, non-potable or a combination system
THINGS TO CONSIDER
Non-potable systems used for landscaping are not suject to watering restrictions
The rainwater harvesting system can be connected to an existing irrigation system.
If you have copper pipes inside your house, a potable system will require a buffering agent
Overhanging trees may require additional filtering or gutter guards
Eaves must be at least 8 feet above grade for a wet rainwater harvesting system to work by gravity-feed
For DIYers, we can design a system that allows you to start small and grow over time
What are your potable/non-potable (landscaping) water needs?
HOW MUCH DOES IT COST?
Do you have space for the storage tanks? A typical 5,000 gallon tank is 11.75 feet in diameter and over 7 feet tall.
Do you have an adequate roof collection surface? Use our rainwater harvesting calculator to find out.
Does your end-use application require a pump? Most drip systems require very little pressure and if you have the right topology, you may not need a pump or you may be able to use a portable pump.
HOAs cannot prohibit rainwater harvesting systems but they can require screening.
Do you have time to monitor the system and perform periodic maintenance?
Each rainwater harvesting system is custom designed for your home, site and water needs. A good rule of thumb is that a system costs between $1.50 to $4.00 per gallon of storage, not including gutters. Dry systems
are less expensive than wet systems
because they do not require burying of pipe and are very simple. The most expensive components of a rainwater harvesting system are storage tanks, piping and trenching. Adding potable treatment costs from $2,000 - $4,000 depending on the volume of water.
Long pipe runs also add to the cost. The following numbers are meant for illustrative and comparison purposes only:
(excludes shipping and installation)
5,000 - 10,000 gallons: $4,000 - $12,500
10,000 - 50,000 gallons: $12,500 - $40,000
$8 - $15 per linear foot for aluminum K-style with leaf screens
$4 - $10 per linear foot
(for pressurized use only) $600 - $5,000
